A brief description of the issue goes here.
After upgrading to Umbraco 8.6.2 it's no longer possible to copy nested content to the clipboard. Both the 'copy all' and 'copy single' functions are broken.
I am seeing this issue on Umbraco version: 8.6.2.
I've also tested it on a clean install, same results.
I'm getting the following reference error:
ReferenceError: Utilities is not defined
at prepareEntryForStorage (umbraco.services.js?cdv=1:917)

This is caused by line 917 in /Umbraco/Js/umbraco.services.js:
var cloneData = Utilities.copy(entryData);
This seems to be related to the fix for issue #7133.

Line 917 in /Umbraco/Js/umbraco.services.js should read:
var cloneData = angular.copy(entryData);
The Utilities collection (/src/Umbraco.Web.UI.Client/src/utilities.js) is not yet included in /src/Umbraco.Web.UI.Client/gulp/config.js:
Tag: release-8.6.2
services: { files: "./src/common/services/**/*.js", out: "umbraco.services.js" },
Branch: v8/contrib
services: { files: ["./src/common/services/**/*.js", "./src/utilities.js"], out: "umbraco.services.js" },
Oh no!
For now this can be manually fixed by replacing line 917 in \Umbraco\Js\umbraco.services.js from var cloneData = Utilities.copy(entryData); to var cloneData = angular.copy(entryData); and then bumping ClientDependency version (just make it 1 higher or lower).
This PR should fix it, error was in using a js class that doesn't yet exist in 8.6 - https://github.com/umbraco/Umbraco-CMS/pull/8226
